A symptomatic mass in the thymus is due to anomalies in the development of the pharyngeal pouches and is also an unusual cause of consultation. These anomalies may be found anywhere along the natural path of the embryonic thymus, from the angle of the jaw to the upper mediastinum.
To review the epidemiology, pathogenesis, diagnosis, and management of congenital anomalies of thymic origin in the neck.
A MEDLINE search was carried out, using the Cochrane methodology, for articles published from January 1980 to January 2007 using the terms "thymus gland," "cervical mass." Following this bibliographical search, the texts considered most relevant by the authors were selected.
While this anomaly is relatively common, its level of presentation is very low and it should always be considered in the differential diagnosis of congenital masses in the neck. New diagnostic imaging techniques provide an early and more accurate diagnosis, thus allowing a better outcome in these patients.
胸腺出现症状性肿块是由于咽囊发育异常所致，也是一种不常见的就诊原因。这些异常可出现在胚胎胸腺自然行程的任何部位，从下颌角到上纵隔。
回顾颈部胸腺源性先天性异常的流行病学、发病机制、诊断及治疗。
采用Cochrane方法，在MEDLINE数据库中检索1980年1月至2007年1月发表的使用“胸腺”“颈部肿块”等术语的文章。在此次文献检索之后，选取作者认为最相关的文献。
虽然这种异常相对常见，但其表现程度很低，在颈部先天性肿块的鉴别诊断中应始终予以考虑。新的诊断成像技术能实现早期且更准确的诊断，从而使这些患者获得更好的治疗效果。
